No full textThis dataset consists of Monte Carlo simulated dose distributions inside 65x62x55 cm3 BluePhantom2 water phantom with PMMA walls for 220 MeV pencil proton beam. Contribution to the absorbed dose is provided separately for protons, photons+electron, and neutrons. Neutron and the total equivalent dose is also provided.
Monte Carlo simulations used the MCNP6.2 code. Libraries used: HLIB=70h NLIB=00c PLIB=14p ELIB=03e PNLIB=70u. Particle cut-off energies used: CUT:P 4 keV, CUT:H 300 keV, CUT:E 2 keV, CUT:T,A,D,S,|,# j 1 MeV. Primary beam: monoenergetic 220 MeV proton pencil beam, beam profile full-width at half maximum = 1.5 cm.

Energy sensitive Timepix silicon detector for electron imaging
No full textWe present the first measurements with the energy sensitive Timepix pixel detector for electron imaging. The hybrid pixel detector consists of a silicon detector, 300 μm thick, bump-bonded to the Timepix readout chip developed by the Medipix2 collaboration (256×256 pixels, 55 μm pitch, 14.08×14.08 mm2 sensitive area). Each Timepix pixel can be independently operated in one of three modes: 1. counting of the detected particles; 2. measurement of the particle energy; 3. measurement of the time of particle interaction. The energy measurement in the second mode is performed via the determination of the ???Time-Over-Threshold??? (TOT). The ionization charge generated by the particle along its track is often registered by several adjacent pixels forming a cluster. The shape of the cluster is affected also by lateral charge spread. It is often possible to determine a particle type, its energy, entrance point and direction by on-line or off-line analysis of shapes of recorded clusters. This way an influence of background or noise can be significantly reduced in measured data.
The energy spectrum for 90Sr/90Y electrons was measured by Timepix detector and compared with the ??- decay spectrum and the Monte Carlo simulated spectrum. In order to improve spatial resolution, we analyze the tracks of all electrons and substitute each cluster with the position of its centroid. We measured the spatial resolution with a 90Sr/90Y source irradiating, at 10 cm distance, a 100 μm thick steel edge slightly tilted with respect to the detector lines. The oversampled Line Spread Function shows a FWHM of 27.5±1.1 ??m. The Timepix Si detector will be used for digital autoradiography with ??- and ??+ tracers, and it could be used for electron microscopy. First tests were performed with a 14C autoradiography sample

All-optical wavelength tuning in Solc filter based on Ti: PPLN waveguide
No full textAll-optical wavelength tuning in a waveguide-type Solc filter based on a Ti:PPLN waveguide has been demonstrated for the first time by ultra-violet illumination. The measured wavelength tuning rate as a function of the UV intensity was about -26.42 nm/W cm(-2).FALSEsciescopu
A Tripartite Post-Recession Rebalancing
No full textIn this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
